Hello again!
I seem to have a problem with a set AO3 stories - they were uploaded/imported from another site. When I try to read on of them on my e-readers, it either shows the whole text on one page (i. e. text of one page overlayed by that of the next pages) or it simply doesn't break the page at the end of the screen (I can see the following line peeking up at the very end of the reader's screen).
I tried re-downloading (overwriting) as well as first-time downloading a few with the latest version of FFF, hoping that it might help. Unfortunately, it didn't work.
Here are two sample links (sorry, they are restricted, I hope you can access them):
story 1
